74F828
74F828 is 10-bit buffer/line driver manufactured by Philips Semiconductors.
FEATURES
74F827, 74F828
- High impedance NPN base inputs for reduced loading (20µA in
High and Low states)
DESCRIPTION
The 74F827 and 74F828 10-Bit buffers provide high performance bus interface buffering for wide data/address paths or buses carrying parity. They have NOR Output Enables (OE0, OE1) for maximum control flexibility. The 74F827 and 74F828 are functionally and pin patible to AMD AM29827 and AM29828. The 74F828 is an inverting version of 74F827. TYPICAL PROPAGATION DELAY 6.0ns 6.0ns TYPICAL SUPPLY CURRENT (TOTAL) 60m A 55m A
- IIL is 20µA vs FAST family spec of 600µA and 1000µA for
AMD 29827/29828 series
- Ideal where high speed, light bus loading and increased fan-in are required
- Controlled rise and fall times to minimize ground bounce
- Glitch free power-up in 3-State
- Flow through pinout architecture for microprocessor oriented applications
TYPE 74F827 74F828
- Outputs sink 64m A
- 74F827 available in SSOP type II package
